[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0025] A floating ball valve stroke measuring tool, the structure of which can be Figure 1-Figure 4In this embodiment, the floating ball valve stroke measuring tool comprises: a base 1, a baffle 2 and a push rod assembly, wherein the base 1 and the baffle 2 are used to provide a positioning basis for the floating ball valve 7 to be tested and other components in the device, and the push rod assembly is used to drive the steel ball 71 inside the floating ball valve 7 to be tested to move, so as to accurately and quickly measure the displacement stroke of the steel ball 71.
[0026] Specifically, a receiving groove 11 is provided on the top surface of the base 1, a first measuring hole 12 connected to the receiving groove 11 is provided at one end of the base 1, and a connecting hole 13 connected to the receiving groove 11 is provided at the other end of the base 1. The baffle 2 is detachably provided at one end of the base 1 provided with the connecting hole 13, and a second measuring hole 21 opposite to the first measuring hole 12 is provided on the baffle 2. The push rod assembly includes a first push rod 3 and a second push rod 4. When assembling, the first push rod 3 and the second push rod 4 should be inserted into the receiving groove 11 along the first measuring hole 12 and the second measuring hole 21, respectively, and a connector 41 for connecting a dial indicator is provided at one end of the second push rod 4 away from the receiving groove 11.
[0027] Figure 5 It is a cross-sectional view of the device in use. When in use, the staff can first place the floating ball valve 7 to be tested inside the receiving groove 11, and then install the baffle 2 on the base 1, so as to clamp and fix the floating ball valve 7 to be tested with the help of the baffle 2 and the inner side wall of the receiving groove 11 to prevent the floating ball valve 7 to be tested from loosening during the measurement process. Then, the detection end of the dial gauge is connected to the connector 41, and the second push rod 4 is inserted into the receiving groove 11 along the second measuring hole 21, so that the second push rod 4 presses the steel ball 71 in the floating ball valve 7 to be tested. Next, the first push rod 3 is inserted into the floating ball valve 7 to be tested along the first measuring hole 12, and the steel ball 71 and the separation pin 72 are driven to move by the first push rod 3. At this time, the reading of the dial gauge will change due to the displacement of the steel ball 71, so the staff can quickly and accurately obtain the measurement result of the displacement stroke of the steel ball with the help of the reading change of the dial gauge.
[0028] As an optional implementation of this embodiment, in order to facilitate the fixation of the base 1 during the measurement process, two positioning clamping surfaces 16 may be provided on the base 1, and the two positioning clamping surfaces 16 should be respectively located at both ends of the base 1. Before use, the staff can clamp the base 1 with flat-nose pliers to prevent the base 1 from moving abnormally during the measurement process, thereby improving the measurement result accuracy of the device.
[0029] In addition, in order to improve the operating convenience of the first push rod 3, an operating pressure head 31 can be further provided at the end of the first push rod 3 away from the accommodating groove 11, so that the staff can apply pressure to the first push rod 3 through the operating pressure head 31 to reduce the difficulty of driving the steel ball 71.
[0030] Optionally, in order to realize the detachable connection between the baffle plate 2 and the base 1, in this embodiment, a first screw hole 14 is further provided at one end of the base 1 provided with the connection hole 13, a first bolt 5 should be provided inside the first screw hole 14, and a positioning hole 22 for accommodating the first bolt 5 is provided on the baffle plate 2. When in use, the staff can install the baffle plate 2 on the base 1 through the first bolt 14, and can adjust the distance between the baffle plate 2 and the base 1 by adjusting the screw-in depth of the first bolt 14, so as to clamp and fix the floating ball valves 7 to be tested of different specifications.
[0031] In addition, in order to improve the connection reliability between the baffle plate 2 and the base 1 and facilitate the staff to disassemble and assemble the floating ball valve 7 to be tested, the base 1 may also be provided with a second screw hole 15 at one end provided with the connection hole 13. The second screw hole 15 should be located on the side of the connection hole 13 away from the first screw hole. A second bolt 6 is provided inside the second screw hole, and an assembly cutout 23 for accommodating the second bolt 6 is provided on the baffle plate 2. When in use, the staff can first install the baffle plate 2 on the base 1 through the first bolt 5, and then install the floating ball valve 7 to be tested into the receiving groove 11. Next, the baffle plate 2 can be driven to rotate with the first bolt 5 as the axis, so that the assembly cutout 23 is clamped on the second bolt 6. In this state, the baffle plate 2 can block the connection hole 13 to prevent the floating ball valve 7 to be tested from being separated from the receiving groove 11. Then the staff can tighten the first bolt 5 and the second bolt 6, so as to clamp and fix the floating ball valve 7 to be tested with the help of the baffle plate 2. When the floating ball valve 7 to be tested needs to be removed from the device, the staff can reversely rotate the baffle 2 to disengage the second bolt 6 from the assembly cutout 23 , thereby facilitating the floating ball valve 7 to be tested to leave the receiving groove 11 along the connecting hole 13 without removing the baffle 2 .
[0032] The effects of the above scheme are described below:
[0033] The present embodiment provides a floating ball valve stroke measuring tool, which can clamp and fix the floating ball valve to be measured through a base and a baffle, and can measure the displacement stroke of the steel ball through the cooperation of a first push rod and a second push rod, thereby reducing the difficulty of measuring the steel ball stroke, improving the efficiency of the measurement work and ensuring that the measurement result has good accuracy.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
